Swollen Thyroid Gland

I woke up this morning feeling a bit of discomfort in my throat and can see from the mirror that the lower part of the larynx seems a little bit swollen then normal so I went to see the doctor. The doctor told me that it’s a swollen thyroid gland and there’s not much he can do until I undergo an ultrasound scan, which I’ll be taking tomorrow. Hopefully it’s not something harmful and that it will go away soon. I’ve heard that some glands (thyroid gland for example) can get swollen if a person is overworked, stressed or tired, which might be the case for me after working like a madman for an oversea project for the past 2.5 week.
